Work bin gate control system of pavement patching machine

The invention relates to a work bin gate control system of a pavement patching machine, comprising a work bin, a discharging nozzle and a gate, wherein the work bin is used for containing road metal, the discharging nozzle is installed at the bottom of the work bin, and the gate is installed on the discharging nozzle, driven by a driving device and used for closing and opening the discharging nozzle. The work bin gate control system is characterized by also comprising a controller and a wind pressure measuring device, wherein the wind pressure measuring device is used for detecting the wind pressure of the discharging nozzle or the wind pressure nearby the discharging nozzle and transmitting signals to the controller, and the controller controls the driving device so as to open or close the gate. According to the work bin gate control system, the wind pressure of the discharging nozzle or the wind pressure nearby the discharging nozzle, and the gate can be opened when the wind pressure is enough, so that the discharging nozzle can be effectively prevented from being blocked, the reliable operation is ensured, the structure is simple and the implantation is simple and convenient.
